My Daughter

So these really weird things started happening to my daughter. At first, when she was younger she told me everything that had happened to her. But now she's 12 and won't say a word. This is one of her most recent experiences:

I'm doing the laundry and all of a sudden she comes up to me and asks "Mom, what was Grandpa like?" I told her that he was a very fun person, and he was very outgoing. Then she asks "What would he say if he saw me now?" I told her what he would say, for me this was weird because my father had only seen her when she was 3 months and then had died of brain cancer, and though all these years she's never asked about him at all.

The next morning she comes up to me and says "Mom, Grandpa's not dead, he talked to me yesterday, he said that I was all grown up and that he would love it very much if he could come over". This really scared me, but it scared me most when I asked "Where did you see him?" She said, "Last night. He was here last night and he told me he was my Grandpa". I thought that's impossible and that maybe she had a dream of him but how she described him fit him perfectly, his voice, how he looked. But she had never seen him before! This Happened when she was 9

A more recent one was this Mother's day:

We had a Mother's Day party at my aunt's house. When everyone had left and the only ones left were my Mom, my daughter, and me, my aunt told us about a call she had gotten a few days back from a PRIVATE number. She didn't pick up but they left a voicemail. I heard it and my mom heard it but I didn't want my daughter to hear it. Because all the voicemail was was a demonically evil laugh of a guy wanting to do harm, it was a scary voicemail. Then, at the end, he whispered, "You're going to pay dearly." And hung up. It was a threat. I didn't tell my daughter about any of it. But when we got home she told me "Mom, when I touched my Aunt's phone I saw a man". Here we go again. I got scared because when I asked her to describe the man her details matched a guy that my Aunt knew perfectly. It turned out that that guy she knew ended up being the one who left the voicemail.

Please tell me what's wrong with my Daughter!

Thanks
